This seems like BASIC FOOTBALL KNOWLEDGE so it should be copied into the Coker thread.
I noticed that the clock ran after that penalty. Was it supposed to? And if it was why not just keep taking penalties until the quarter ends (aka keep taking penalties until the quarter ends. Since you're backed up it really doesn't hurt you.)
My guess was that the clock isn't supposed to restart after the penalty and their was a mistake because then a team could just run down the clock like I suggested.
